* DebugInfo: Fix ordering of members after r191928David Blaikie2013-10-045-6/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the case (shown in the attached test) where a member function definition was emitted into debug info the following could occur: 1) build the debug info for the member function definition 2) in (1), build the debug info for the member function declaration 3) construct and add the member function declaration DIE 4) add it to its context 5) build its context (the type it is a member of) 6) construct the members and add them to the type 7) except don't add member functions because "getOrCreateSubprogram" adds the function to its parent anyway 8) except we're only partway through building this subprogram declaration so it hasn't been added yet - but we returned the partially constructed DIE (since it's already in the MDNode->DIE mapping to avoid infinitely recursing trying to create the member function DIE) 9) once the type is constructed, add the member function to it 10) now the members are out of order (the member function being defined is listed as the last member, even though it was declared as the first) To avoid this, construct the context of the subprogram DIE before we query to see if it exists. That way we never end up creating it before creating its context and ending up in this situation. Alternatively, the type construction that visits/builds all the members could call something like getOrCreateSubprogram, but that doesn't ever do the "add to context" step. Then the type building code would always be responsible for adding members (and the subprogram "addToContextDIE" would no-op because the context building would have added the subprogram declaration to the type/context DIE already). (the test cases updated were overly-sensitive to offsets or abbreviation numbers. We don't have a nice way to make these tests more robust as yet - multiline FileCheck matches would be required) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191939 91177308-0d34-0410-b5e6-96231b3b80d8

* Fixed a bug with section names containing special characters.Richard Mitton2013-10-033-44/+51
| | | | | | | | | | Changed the dwarf aranges code to not use getLabelEndName, as it turns out it's not reliable to call that given user-defined section names. Section names can have characters in that aren't representable as symbol names. The dwarf-aranges test case has been updated to include a special character, to check this. This fixes pr17416. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191932 91177308-0d34-0410-b5e6-96231b3b80d8
* Pull fptrunc's upwards through selects when one of the select's selectands ↵Owen Anderson2013-10-032-0/+25
| | | | | | was a constant. This has a number of benefits, including producing small immediates (easier to materialize, smaller constant pools) as well as being more likely to allow the fptrunc to fuse with a preceding instruction (truncating selects are unusual). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191929 91177308-0d34-0410-b5e6-96231b3b80d8
* DebugInfo: Avoid redundantly adding child DIEs to parents.David Blaikie2013-10-033-15/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DIE::addChild had a shortcircuit that silently no-op'd when a child was readded to the same parent. This hid some quirky/redundant code in DwarfDebug/CompileUnit. By removing that functionality and replacing it with an assert I was able to find and cleanup those cases, mostly centering around adding members to types in various circumstances. 1) The original oddity I noticed while working on type units (which actually was helping me in the short term, by accident) was the addToContextOwner call in constructTypeDIE. This call was completely bogus (why was it only done for non-virtual types? what relevance does that have at all) and redundant with the more uniform addToContextOwner made in getOrCreateTypeDIE. 2) If a member function definition was visited (createSubprogramDIE), it would attempt to build the member function declaration. The declaration DIE would then be added to its context, but in building the context (the type for which this function is a member) the members of the type would be added to the type automatically, so by the time the context was constructed, the member function was already associated with it. 3) The same as (2) but without the member function being constructed first. Whenever a type was constructed, the members would be created and member functions would be created by getOrCreateSubprogramDIE - this would lead to the subprogram being added to the (incomplete) type already, then the general member-construction code would add it again. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191928 91177308-0d34-0410-b5e6-96231b3b80d8

* Optimize linkonce_odr unnamed_addr functions during LTO.Rafael Espindola2013-10-0312-23/+124
| | | | | | | | | | | Generalize the API so we can distinguish symbols that are needed just for a DSO symbol table from those that are used from some native .o. The symbols that are only wanted for the dso symbol table can be dropped if llvm can prove every other dso has a copy (linkonce_odr) and the address is not important (unnamed_addr). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191922 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove wild .debug_aranges entries generated from unimportant labelsAlexey Samsonov2013-10-034-22/+98
| | | | | | | | | | | | | | | | | r191052 added emitting .debug_aranges to Clang, but this functionality is broken: it uses all MC labels added in DWARF Asm printer, including the labels for build relocations between different DWARF sections, like .Lsection_line or .Ldebug_loc0. As a result, if any DIE .debug_info would contain "DW_AT_location=0x123" attribute, .debug_aranges would also contain a range starting from 0x123, breaking tools that rely on this section. This patch fixes this by using only MC labels that corresponds to the addresses in the user program. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191884 91177308-0d34-0410-b5e6-96231b3b80d8
